Abstract

본 발명은 칼라 음극선관용 전자총을 개시한다.The present invention discloses an electron gun for a color cathode ray tube.

본 발명은 최종가속전극과, 이 최종가속전극과 결합되며 그 바닥면에 세개의 전자빔 통과공이 형성된 저면이 막힌 원통형의 쉴드컵을 구비하여 된 칼라 음극선관용 전자총에 관한 것으로, 상기 쉴드컵의 내면에 편향자계의 누설자계를 차폐하는 차폐수단이 마련된 것에 그 특징이 있으며, 이는 편향요오크의 누설자계에 의해 전자빔이 왜곡되는 것을 방지할 수 있는 이점을 가진다.The present invention relates to an electron gun for a color cathode ray tube having a final accelerating electrode and a cylindrical shield cup coupled to the final accelerating electrode and having a bottom surface formed with three electron beam through holes formed on the bottom thereof. The shielding means for shielding the leakage magnetic field of the deflection magnetic field is provided, which has the advantage of preventing the electron beam from being distorted by the leakage magnetic field of the deflection yoke.
